Hello everybody,

I have mount, one ET200s, in  slot I have mount the next board 6ES7 135-4GB01-0AB0 (2ao st1), I have mounted in terminal board 6ES7-193-4CB20-0AA0, in the Q address direction I have 368....371,  What is my problem I can´t to see any value?, I put 20000 in the AW368, and measure in the terminals 1 and 3 of terminal board, but I don´t measure anything.

Thank you for your help.

Hello, Marcjan and Thank your for your answer.

Ok, I have one ET200s Im151-8 pn/dp cpu, then it isn´t peripheral device, this device is a Cpu like for example a Cpu 315 pn/dp of S7-300.

Then in Device configuration, the Q address is 368....371, then I thought that the direction of ch1 of the board is AW368 and AW370 for ch2, I Tried to put PAW368 or PAW370 in a Watch table but it give me to fault. Do you have any idea?

I use a board 2ao st1 (6es7 135-4gb01-0ab0) with terminal board (6es7 193-4cb20-0aa0), and I measure between terminal 1 and 3 for ch1, and terminal 5 and 7 for ch2.

Thank.

Ok, guys

I could solve my problem, it was very strange but I change all the directions of my system, next download my project to cpu, and so analog output as analog input start to work.

thank you. bye.
